Overview of Rotary Screw Compressor
If you’re wondering how a rotary screw air compressor works, you’ve come to the right place. Unlike reciprocating compressors which use pistons to compress air, screw compressors use rotors that interlock, trapping air between them to compress it. As the screws rotate, the volume of air between them decreases, increasing the pressure of the air which is then discharged out of the compressor.
The design of the screw compressor is ideal for continuous use and efficient energy consumption as there are no metal-to-metal movement or pressure pulsations that create wear and tear. In fact, screw compressors can deliver a steady stream of compressed air without any fluctuations that may impact production efficiency. Overall, the screw compressor is an excellent choice for applications that require large volumes of compressed air at a consistent pressure.
What is a Rotary Screw Compressor?
A rotary screw compressor is a type of gas compressor that works based on the principle of two interlocking helical rotors. These rotors rotate in opposite directions and compress the gas trapped between them. The compressed gas then exits the compressor through a discharge port.
